Measurement of health disparities is a key component for the assessment of health systems. The extent to which disparities in health are systematically associated with income has been proposed as a measure of disparities in realized health outcomes. One aspect which hitherto has received limited attention is the risk people face about their future health. We introduce a concern about risky health prospects into the standard measurement apparatus used by health economists; and argue that a reasonable assessment of inequalities in ex-ante risk considers inequalities in expected health and inequalities in the dispersion of future health prospects. Using data from the Australian Household, Income and Labour Dynamics in Australia (HILDA) Survey from 2002 until 2013, we find that the poor were not only expected to lose more health than the rich over time but they also faced greater risk about their future health prospects than the rich.
